StreamMessageBubble class

A styled container that wraps message content with a themed background, shape, and padding.

StreamMessageBubble is the visual shell of a chat message. Metadata, reactions, and reply indicators compose around it at a higher level.

If a StreamMessageLayout is found in the ancestor tree, style properties automatically adapt to the current message layout.

{@tool snippet}

)

{@end-tool}
